The positive electrode assembly 6 and negative electrode assembly 7 have rivets, and the rivets will be riveted to the pressure blocks after the battery cover assembly is assembled.

[0003] In existing technologies, battery cover assembly typically involves multiple processes and is assembled manually. In particular, the assembly of the cover itself requires manual insertion of the positive and negative electrode components through two mounting holes. This process necessitates manual material loading and assembly, resulting in high labor costs and low production efficiency, making it difficult to meet production demands. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a battery cover loading device, which solves the problems of high labor costs and low assembly efficiency of manual battery cover loading.

The fixing block is horizontally slidably connected to a slide rail fixed at the bottom of the carrier plate via a slider. The output end of the pushing cylinder is connected to the fixing block. The pushing block is fixedly installed on the side of the fixing block. The carrier plate has a clearance hole to facilitate the upward passage of the pushing block.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] A preferred embodiment of this utility model provides a battery cover plate feeding device, which is mainly used to meet the automatic feeding requirements of battery cover plates 8 on a fully automated battery cover plate assembly production line.

[0019] For details, see Figure 1 The feeding device mainly consists of three parts: a cover plate feeding unit 1, a feeding gripping mechanism 2, and a positioning mechanism. The positioning fixture 5 is located between the cover plate feeding unit 1 and the feeding gripping mechanism 2, and is located below the feeding gripping mechanism 2.

[0020] The positioning fixture 5 has corresponding positioning grooves 331 and positioning holes. Before placing the cover plate 8, the positive electrode assembly 6, the negative electrode assembly 7, and the bracket have been placed onto the positioning fixture 5 in sequence (see...). Figure 8 (The bracket is hidden below the cover plate 8). Therefore, when the positioning fixture 5 moves to the location of the battery cover plate 8 feeding device, it will place the cover plate 8 onto the positioning fixture 5.

[0021] like Figures 2-5 As shown, the cover plate feeding unit 1 mainly consists of a support 14, a carrier plate 11, a hopper 13, and a pushing mechanism 12. The carrier plate 11 is fixedly installed on the top of the support 14, the pushing mechanism 12 is located below the carrier plate 11, and the hopper 13 is installed on the carrier plate 11.

[0022] The hopper 13 consists of two limiting blocks 131. The two limiting blocks 131 are arranged opposite each other and are vertically fixed on both sides of the carrier plate 11. A first limiting groove 1311 is formed on the opposite side of the two limiting blocks 131. The first limiting groove 1311 is vertically connected so that the cover plate 8 enters the first limiting groove 1311 from the upper end of the limiting block 131 and then flows out from the bottom of the first limiting groove 1311.

[0023] Several cover plates 8 are stacked between two limiting blocks 131, and the two ends of the cover plates 8 are respectively embedded into the first limiting grooves 1311 on the two limiting blocks 131.

[0024] See Figure 5 A second limiting groove 111 is provided in the middle area of ​​the upper surface of the carrier plate 11. The width of the second limiting groove 111 is adapted to the length of the cover plate 8, and the depth of the second limiting groove 111 is adapted to the thickness of the cover plate 8. Two limiting blocks 131 are respectively located above the two sides of the second limiting groove 111. The cover plate 8 in the hopper 13 will fall downward into the second limiting groove 111. Generally, the cover plate 8 at the bottom will fall into the second limiting groove 111.

[0025] like Figure 4As shown, the pushing mechanism 12 mainly consists of a pushing cylinder 122, a fixing block 124, and a pushing block 123. The pushing cylinder 122 is horizontally fixedly installed at the bottom of the cylinder fixing seat 121, which is fixed to the side of the carrier plate 11 away from the positioning fixture 5.

[0026] A slide rail is provided at the bottom of the carrier plate 11, and the fixing block 124 is horizontally slidably connected to the slide rail via a slider. The output end of the pusher cylinder 122 is connected to the fixing block 124. A pusher block 123 is provided on each side of the fixing block 124, and the pusher block 123 is fixedly connected to the fixing block 124 by screws.

[0027] The pusher block 123 extends upward and passes through the clearance hole 112 on the carrier plate 11, extending into the second limiting groove 111. However, the height of the upper surface of the pusher block 123 does not exceed the height of the upper surface of the cover plate 8 located in the second limiting groove 111. The extension direction of the clearance hole 112 on the carrier plate 11 is consistent with the pushing direction of the pusher cylinder 122.

[0028] The pusher cylinder 122 controls the pusher block 123 to move closer to or further away from the positioning fixture 5. When the pusher block 123 moves, it will push the cover plate 8 located at the bottom of the hopper 13 out of the hopper 13 and move towards the positioning fixture 5, and finally be blocked by the blocking block 15.

[0029] like Figure 3 As shown, the blocking block 15 is fixedly installed on the side of the carrier plate 11 near the positioning fixture 5 to prevent the cover plate 8 from sliding out of the second limiting groove 111. The blocking block 15 will block the middle area on one side of the cover plate 8.

[0030] Once the cover plate 8 is in place, the feeding and gripping mechanism 2 will move into place and grip the cover plate 8, and then place the cover plate 8 onto the positioning fixture 5.

[0031] like Figure 7 As shown, the feeding and gripping mechanism 2 mainly consists of a fixed frame, a front-to-back moving cylinder 21, a cylinder fixing plate 22, a lifting cylinder 23, a T-shaped plate 24, and two finger cylinders 25. The front-to-back moving cylinder 21 is horizontally fixed on the fixed frame, and its output end is connected to the cylinder fixing plate 22. The lifting cylinder 23 is vertically fixed on the cylinder fixing plate 22.

[0032] The lifting cylinder 23 is a sliding cylinder, and the T-shaped plate 24 is fixedly mounted on the sliding cylinder, which controls the up and down movement of the T-shaped plate 24. Two finger cylinders 25 are vertically fixed on both sides of the T-shaped plate 24, and each finger cylinder 25 has two grippers 26 for gripping the cover plate 8. The two finger cylinders 25 control the grippers 26 to grasp the parts of the cover plate 8 near both ends.

[0033] The forward and backward movement cylinder 21 controls the finger cylinder 25 to extend forward and move to directly above the cover plate 8 to be grasped on the carrier plate 11. Then, the lifting cylinder 23 controls the two finger cylinders 25 to move downward, and the finger cylinders 25 control the two grippers 26 to close and grasp the cover plate 8. The clearance hole 112 on the carrier plate 11 will provide clearance for the grippers 26, making it easier for the grippers 26 to clamp the sides of the cover plate 8.

[0034] After the cover plate 8 is gripped, the feeding gripping mechanism 2 will move the cover plate 8 directly above the positioning fixture 5.

[0035] See Figure 1 Before the cover plate 8 is placed on the positioning fixture 5, the left positioning mechanism 3 and the right positioning mechanism 4 will position the positive electrode component 6 and the negative electrode component 7.

[0036] The structures of the left positioning mechanism 3 and the right positioning mechanism 4 are identical. In this embodiment, the left positioning mechanism 3 will be used as an example.

[0037] like Figure 2 As shown, the left positioning mechanism 3 consists of a positioning cylinder 31, a Y-shaped plate 32, and two positioning plates 33. The positioning cylinder 31 is horizontally positioned. The positioning cylinder 31 in the left positioning mechanism 3 is fixedly mounted on a support plate below the carrier plate 11. The output end of the positioning cylinder 31 is connected to the Y-shaped plate 32, and the two positioning plates 33 are horizontally fixed on both sides of the top of the Y-shaped plate 32. The two positioning plates 33 correspond to the positive electrode assembly 6 and the negative electrode assembly 7, respectively.

[0038] See Figure 6 Two semi-circular positioning grooves 331 are formed on the front end face of each positioning plate 33. The positioning plates 33 in the left positioning mechanism 3 and the right positioning mechanism 4 are at the same horizontal height, and their height is adapted to the height of the rivets on the positive electrode assembly 6 and the negative electrode assembly 7 on the positioning fixture 5. The shape of the positioning grooves 331 is adapted to the shape of the rivets.

[0039] The positioning cylinder 31 controls the positioning plate 33 to approach the rivet, and then the two positioning plates 33 clamp the rivet. The semi-circular positioning groove 331 is used to fine-tune and position the positive electrode component 6 and the negative electrode component 7 relative to the positioning fixture 5, so that the feeding gripping mechanism 2 can accurately place the cover plate 8 on the positioning fixture 5, while ensuring that the positive electrode component 6 and the negative electrode component 7 can accurately pass through the mounting holes on the cover plate 8.

[0040] like Figure 8As shown, when the cover plate 8 approaches the positive electrode component 6 and the negative electrode component 7, and the positive electrode component 6 and the negative electrode component 7 partially pass through the mounting holes on the cover plate 8, the left positioning mechanism 3 and the right positioning mechanism 4 will control the positioning plate 33 to return to its original position so that the cover plate 8 can fall onto the positioning fixture 5, and the positive electrode component 6 and the negative electrode component 7 can completely pass through the mounting holes on the cover plate 8, thus completing the loading and assembly of the cover plate 8.

[0041] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
